ATOMIZER.

SPECIFICATION forming part of Letters Patent No. 378,357, dated February 21, 1888.

Application filed March 3 1586. Serial No.1!l7,.ll3. rhloilclJ To all 2071,0712. it may concern:

Be it known that I, ALLEN Du Vrnnrss, a citizen ofthe United States, residing at Toledo, in the county of Lucas and State of Ohio, have invented a new and useful Spray-Producer, of which the following is a specification.

My invention relates to improvements in atomizers for making local applications of fluids, either medicated or otherwise, in an atomized or sprayed form; and the object to be attained is the production of a small, convenient, self-contained, and effective instrument which shall be especially adapted for the treat ment of diseases of the throat and nasal cavities, and which shall combine the following elements: a fluid-receptacle and a fluid-conveying tube connecting with the interior of the said receptacle; an air-tube lying substantially parallel with the said fluid tube, and being adapted at one end to be connected with a compressed-air supply. Attached to said airtube is the aforesaid fluid'receptacle, with the interior of which it connects by means of an orifice. At the opposite extremity from the air-supply of the air-tube, and disposed between the said extremity and the corresponding extremity of the fluid-tube, is a revolving spray-produciug head, which head is adapted to be rotated in a plane between said tubes, the axis of which plane is at right angles to the line of the said tubes. These objects I attain by the mechanism illustrated in the accompanyiug drawings, in which- Figure 1 is a view of a spray-producer embodying my improvements, all of which view is shown in perspective except the receptacle A, which is shown in section. Fig. 2 is an enlarged sectional view of the receptacle A, having a part of its rear wall cut away for the purpose of exhibiting the hole B in the tube 0. The same hole,B,extends through the wall (when it is not cut away, as shown) of the receptacle A, connecting the interior of the tube 0 with the interior of the receptacle A. Fig. 3 is an enlarged side view on line D. Fig. 4, of the spray-producing head, having its adjust ing movements illustrated by the arrows. Fig. 4 is an enlarged sectional view of the spray producing end, taken on line E, Fig. 3.

In Fig. 1, 0 represents an air-conducting tube, which, by means of the flexible pipe F, is connected with any mechanism for supplyingcompressed air. A represents a receptacle, and is attached to the tube 0, as shown in Figs. 1 and 2. In. Figs. 1 and 2 are also shown a fluid-carrying tube, G, which is also attached to the receptacle A, passing into the same near its top, and, curving downward, extends to nearly the bottom of said receptacle. Near the head H the tubes 0 and G separate in such a manner as to inclose the head H and make connection with its air and fluid passages, as shown in-Fig. 4:

B in Fig. 1 represents a hole in the wall of the receptacle A, connecting with a similar hole, 13', through the wall of the tube G. The objectof these holes is to allow the passage of air from the tube G to the receptacle A.

The operation of this device is as follows: The head H having been turned in any de sired direction, as indicated by the arrows l I in Fig. 3, and the desired fluid placed in the receptacle A, and the tube C, through the medium of the pipe F, connected with any suitable couipressed-air supply, the instrument is ready for use. The instrument is then grasped in the hand of the operator in such a manner as to admit of the thumb being placed over the top of the receptacle A, for a purpose which will be hereinafter fully explained. When it is desired to use this instrument in the ordinary manner, (after the preparation above described has been made,) it is only necessary to let on the compressed air, which, rushing through the tube G and out of the passage-way K across the fluid-passageway L, produces a partial vacuum at L, when the atmospheric pressure upon the surface of the fluid in the re ceptacle Aforccs thesaid fluid through the tube G and out of the passage-way L, where it is vaporized in the open atmosphere. In this case no pressure greater than the atmospheric pressure is brought upon the surface of the fluid in the receptacle A. Now, when it is de sired to increase this pressure for the purpose of throwing a larger quantity of fluid, and without mingling any increased quantity of air with the said fluid, as hereinbefore set forth, it is only necessary to place the thumb over the top of the receptacle A. This closes or partially closes the said receptacle, thus retaining the air passing through the hole B within the receptacle A, where it presses upon the surface of the fluid contained in the receptacle ICO ' A with an increased pressure above the atmospheric pressure before described, and forces an increased quantity of fluid through the conducting-tube G to the opening L, where it is atomized.

It is obvious that other means than the thumb may be used as a cover for the receptacle A, such as the finger, some portions of the hand, or even a material cover.

Having described my invention, I do not claim, broadly, a spray-producer which is adapted to throw a spray in only one direction, nor aspray-producer having a revolving spray-producing head which revolves upon an axial line which is substantially parallel to the {lirection of the air and fluid conducting tubes;

That I claim as new, and desire to secure by Letters Patent, is

A liquid -receptacle located upon an air- 20 the line of the said tubes, substantially as shown and described.
